<h2>Message</h2>
<div class="docbody">
<p>Feed uses an obsolete namespace</p>
</div>
<h2>Explanation</h2>

<div class="docbody">
<p>This feed is using an obsolete namespace used by an obsolete snapshot of Atom, which is not supported by this validator.</p>
</div>
<h2>Solution</h2>
<div class="docbody">
<p>Early adopters of the Atom format should upgrade their feed to conform to <a href="http://www.ietf.org/rfc/rfc4287">RFC 4287</a>.</p>
<ul>
<li><a href="http://www.blogger.com/">Blogger</a> users with access to PHP can use <a href="http://www.atomenabled.org/2006/07/atomenabled-bloggers.php#115334590123672226">these instructions</a>.</li>
<li><a href="http://www.sixapart.com/movabletype/">MovableType</a> users may want to consider upgrading to <a href="http://www.sixapart.com/movabletype/docs/3.2/h_changelog/3_2.html">version 3.2</a>.</li>
<li><a href="http://wordpress.org/">WordPress</a> users can use either
<a href="http://www.snellspace.com/wp/?p=404">these drop in replacement templates</a>, or
<a href="http://benjamin.smedbergs.us/wordpress-atom-1.0/">this plugin</a>.</li>
</ul>
<p>If you are looking to validate an Atom 0.3 feed,
<a href="http://www.validome.org/rss-atom/">this validator</a>
provides support for Atom 0.3.</p>
